bug: the use of np.fft.fftshift

[Jarrome]

Hi, I find a bug in calculateFft. The input of your np.fft.fftshift is a [,,2] array which is not as array [,] of complex number in np. When I change imgFft to array of complex, the script expired to produce correct result. What is the problem of that function, why does it works well with a not suitable feedin?

do you get the right result? how you change imgFft to array of complex?i met the problem :TypeError: Expected cv::UMat for argument 'src'

[Jarrome]

No, it seems happen to be right in the example.

Sry, I didn't meet TypeError: Expected cv::UMat for argument 'src'.

But this script is nice to make the idea of FMI clear. I write my own and works well. ;)

thank you ,i fixed the problem, the probelm is at the input. sys.argv is bad to import my image. i change the way to input my parameters. and the code does well.
